Cornerstone Home Design

Cornerstone Home Design is based in South San Francisco, CA, and brings a well-rounded approach to kitchen and bath renovation with countertop fabrication, installation, and cabinetry all under one roof. With 168 reviews and a 4.5-star rating, they're one of the more established shops on the Peninsula. South San Francisco's proximity to both San Francisco and the mid-Peninsula makes it a convenient stop for homeowners across a wide stretch of the Bay Area. Their combined countertop and cabinetry offering appeals strongly to customers doing full kitchen remodels.

Cornerstone Home Design covers custom countertop fabrication from template through installation, working with materials like granite, quartz, and marble. Their edge profiling service gives customers control over the finished look, whether that's a clean straight edge or a more decorative profile. Sink cutouts are handled as part of fabrication, sized precisely for undermount or drop-in configurations. Because they also offer cabinetry services, customers doing full kitchen remodels can coordinate countertops and cabinet installation in one place, which simplifies scheduling and keeps the project moving without waiting on multiple contractors.

A shop that handles both cabinetry and countertops is genuinely useful for full kitchen remodels, where the fit between cabinets and counters is the most visible part of the finished product. Cornerstone's volume of reviews, the most of any fabricator on this Peninsula list, suggests they've built a real track record with local homeowners. That kind of history matters when you're making decisions about a high-cost kitchen upgrade.

Your project with Cornerstone typically starts with a free estimate where you discuss layout, material preferences, and whether you need cabinetry work alongside the countertops. Once you've locked in your selections, a template appointment is scheduled to capture precise measurements of your kitchen or bathroom. The fabrication team then cuts and profiles your stone in the shop before delivering and installing it in your home. Because they handle cabinets too, they can sequence the work so your countertops drop in right after cabinet installation, minimizing downtime in your kitchen.

Cornerstone Home Design serves South San Francisco and surrounding Peninsula communities, including Daly City, San Bruno, Millbrae, and Burlingame. They're positioned well to reach customers from San Francisco down to Redwood City, making them a practical option for homeowners throughout San Mateo County.
